The lambda (λ) is an iconic symbol of the Half-Life series, forming part of the logo for all of the games to date, being displayed on the chest of the HEV suit, and signifying the resistance movement in Half-Life 2 and it’s episodes, not to mention being the main logo of a certain Valve fansite.

Like any story with its depth and complexity, the Half-Life series leaves a lot to the imagination. In fact, considering the latest installment’s cliffhanger, it leaves more to the imagination than anyone wants.

Do you want to learn more about Half-Life? To see the obscure? To witness the oddities? Then you’ve come to the right playlist!

The ‘Half-Life Fact Files’ is a small project by Rikki D’Angelo or more well known to the Half-Life community as Marphitimus Blackimus (or Marphy Black for short).

Self-described as ”an instalment in this series of Half-Life educational film strips”, the project is focused on exploring the outlandish knowledge, obscurities and fascinations that lie behind the very fabric of Half-Life.
